Specification of Letters Patent. Application filed March 1906. SerialNo. 3 04.058

Patented June 19, 1906.

'o all whom it iitaylcortcern:

Be it known that I, SPENCER OTIS, a citizenof the United States,residing at Chicago,

in the countyof Cook and State of Illinois, have invented certain newand useful 1m provements in Dump-Oars, of which the folowing is .aspecification.

My. invention relates to dump-cars of the i type which has a bottomcomprising hinged "videan' improved locking meansfor the dumping-doors,and has for itsfobject to produmping-doors which may not be tamperedwithyby any.unauthorized person. My invention consists in thecombinations and details hereinafter described and claimed.

' r ln'thegaccompanymg drawings, Figure 1 is a transverse section of aortion of a car, showing my invention app led thereto.- Fig.

2fi's an enlarged detail view of the locking device. Fig. 3 isa view.similar to Fig, 2

In the accompanying drawings, (it indicates the dum' ing-door hingedtothe center sill of a car. v is a 'bar movable longitudinally of drepresentcompound lever mechanism connected wan operating-shaft e formoving the bar I). f is a Wedge-track 'havin a-hor1zon-, tal endportion. f againstwhic the bar I) rests 'When the door is 111 closedposition.

' Theseelements form no part of'my. present Invention.

'The transverse members .of .the car frameare provided with inclinedmetallic tracks g,

. having a lower horizontal portion 9 and an upper recess'ed portion 9The operating bar 6 travelson .this track opening and closing the door,aswill' be readily understood.

When the doorisin closed pos1tion,"the bar .rests'in the recessed ortiong, and it is de-,

sira'ble to provide a H ,ocking device to-retain the bar inthisposition. For this'dpurpose I provide a pivoted gravity latch or 0pivfeted at h above-the lockih .-bar'w en the I shown in Figs '1 and 2,the tendencyof the gravity-latch h is to fall inward't'oward' the centerof'the car! owing to the eccentric locarovidedat 72,

- tion of this'piv'ot h. To prevent this inward movement to. anyundue.extent, I- provlde a stop-pint. in the transverse members, It

- be understood'that by this construction positionshown in Fig. 2.

e parts shown in Figs. 2'

the operating-bar b as it ap teaches the lock ing-dog will lift the sames ightlyand cause the dog to 'ride over the operating-bar in the Tosecurely lock the door in this position, I provide a lockin 7 pin 7:,which passes throu h perforations in the transverse frame of t e car andinthe upper end of the locking-dog, these perforations being in registerwhen the partsarein locking position. This pin may be attached to thecar-frame by a chain k and is provided at its opposite end withaperforationk for the reception "of an ordinary sealing devl'ce, such asis commonly used on rallroadcars. ,The locking-pm k serves to preventany movementof the dog while the pin is in looking position, and. thispin after" the seal has been a plied can not be withdrawn with outbreaking the seal, thus preventing the unauthorized operation of thedumpingdoorsf The operation of my invention will be readilyunderst'oodwithout further ,description. I claim-- 1 1 1. "A dump-carhavinga bott m comprisin a hin ed door, means movab e longitudi na ly ofthe door to open and close the door, a track supporting the-door-ojmratin means, and a gravity-latch pivoted above the track andengaging the door operating' means when the door'is inclosed position.2; A dump-car having a bottom compris ing a hinged dumping-door, meanscomprising a transversely-moving bar for operating the door, a latchpivoted to one of the trans verse members of'the car-frame'and'eng'ag'ing' the bar for locking the door-operating"rrieans peringtherewith.
